RISE is built on the premise that policies matter along with good institutions and enforcement. RISE is based on a wealth of empirical evidence which shows that polices and regulations matter when countries are seeking to attract investment and establish a sustainable energy agenda. Therefore, it is relevant to assess the existence of policy and regulation to understand the investment environment for sustainable energy. However, there may be many factors that influence investment decisions, from the existence of good practices, to quality and content of the policies, and their actual enforcement.
